We all know the importance of fast load time for good SERP. Google has also confirmed that core web vitals will be part of Google’s algorithm starting in 2021. So, you should always try to improve the PageSpeed score of your web pages. You can use Google’s PageSpeed Insights tool to check the score of your pages and get suggestions for optimization. Whenever you check for a web page, the most common suggestion shows “Eliminate render-blocking resources”.
Here’s a screenshot of PageSpeec score suggestions showing the error “Eliminate render-blocking resources.”

What are render-blocking resources?
Now after the plugin combines all JS files into one and all CSS files into one, your website may still have a Render Blocking Resource issue if CSS and JS files are larger in size. In this case, you need to remove unused CSS codes from the CSS file. I have written a detailed article on how to remove unused CSS from the blog.
It will surely reduce the render time and in the best case remove the Render-Blocking Resources warning. If you are also using Google Adsense or other ads script on your web page, it is really hard to completely remove the render blocking scripts because Ads also load their script and CSS. This is the reason scoring a perfect 100 with Ads isn’t possible. But you need to try to improve as much as possible.
Website speed is now a critical factor in the website’s ranking on Google. So, you should always try your best to reduce the load time. CSS, JS, and images affect the load time most. I have written several articles on WordPress optimization. If you need help, read those articles.
